Won't that consistency be difficult to manage if I don't have a concrete vibrator?

As long as you dont see too much water separated on your concrete mix thats ok.

It's not just recommended but required, sir. Drier, stronger mixes won't flow well. The proper way to prevent air bubbles, voids & honeycomb is thru proper vibration. It's even wise to keep a spare ready upon pouring as vibrator failures can be quite common.

For 1:2:3 workable mix you can get 4000-5000 psi. You can try 1:3:4 for 3000-3500psi. Sometimes on sacks method not all are filled equally. Like what trav said water is a major factor for concrete strength.

At a nearby house under construction, the engr told me she was using 1:4:6 for structural citing the sacks don't really get filled, but I think that would be more like 1:3:5. Just thinking that maybe if I do 1:2:4, then that would be more like 1:1.5:3?

Actually gusto no foreman equal parts sand and gravel para daw iwas voids sa column, ano kaya effect nito sa strength?

If in doubt & you've the time to do some R&D, you can have your sample mixes lab-tested for compressive strength.

Haha this is getting too meticulous. Maybe what I'll do is to keep a sample for testing later, I read that concrete achieves 99% strength in 28 days and continues to go beyond it's "rated" strength as years go by.

Thanks, sir. Not qualified a master though. That honor should go to max.

Guys what's the best way to anchor wooden baluster railing to tiled stairs? The stair tiles are outdoor finish porcelain types.

Original plan was to have stainless steel railing but I'm trying to save a bundle by using wood.
